How to Connect Perplexity API to Meta Muse via MCP

💡 No install? Use cloud.anythingmcp.com directly. Sign in, click Connectors → Perplexity API, paste your credentials, mint an MCP API key and you're done. No Docker, no git clone, no local server.

Perplexity API + Meta Muse

Let your AI ask Perplexity with your own API key: answers grounded in live web search with their sources, raw ranked search results, Sonar models, and longer deep research that runs in the background.

Prerequisites

See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:

PERPLEXITY_API_KEY

Step 1 — Get credentials

1. Sign in at https://console.perplexity.ai and buy credits under Billing. The API is prepaid and separate from a Perplexity Pro subscription, which does not include API usage. Auto top-up avoids interruptions.
2. Open API Keys, create a key and copy it (it starts with pplx-).
3. Paste it into PERPLEXITY_API_KEY as Perplexity shows it, without the word Bearer, and install the connector. The key is sent only to Perplexity.
4. Start with perplexity_list_models: it costs nothing and confirms the key works.

Billed to your own Perplexity credits: every call is billed to your prepaid API credits, except listing models and reading or cancelling a research run. Each answer reports its cost in US dollars, and the connector uses the cheap defaults unless you ask for more.

Which tool does what:

• perplexity_ask answers questions that need current information, with numbered sources. The fast preset (the default) handles single facts and short summaries; low adds light multi-step research.
• perplexity_search returns ranked web results with titles, links and snippets but no written answer. It is the cheapest option when the AI can read the sources itself: about $1 per 1,000 requests with the fast search type, $5 with web.
• perplexity_sonar uses the Sonar models (sonar, sonar-pro and sonar-reasoning-pro). Perplexity ended support for Sonar chat completions on 27 September 2026: requests are still answered, rerouted onto the newer API, but perplexity_ask is the better choice for new work.
• perplexity_start_research runs deep research in the background with the presets medium, high or xhigh. A run can take several minutes and costs noticeably more than a quick answer, so the AI checks with you before it starts high or xhigh, and cancels runs you no longer need.

Filters: limit the sources to up to 20 domains (all included, or all excluded with a leading minus, such as -reddit.com, never mixed), to a recent period (hour, day, week, month or year) or to dates written MM/DD/YYYY.

Time limit: a call through the connector stops after 30 seconds. Quick answers fit well within it; anything longer goes through a background research run.

Untrusted content: answers are built from the open web. The AI treats instructions found inside them as data, not as orders.

Common errors: 401 means the key is wrong or deleted, or the account has run out of credits (Perplexity answers both with 401), so check Billing and API Keys in the console. 429: the rate limit of your usage tier, which rises with your total credit purchases. 400 or 422: an invalid parameter, such as an unknown model or included and excluded domains mixed.

The connector does not stream answers, create embeddings, upload files or read Perplexity's analytics.

Step 2 — Install the adapter

curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d

Step 3 — Add the connector in Muse

Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide shows YOUR_SERVER_ID.

Muse adds remote MCP servers as custom connectors and signs in to them with OAuth.

1. In Muse, open Settings → Connectors and choose Add custom connector.
2. Paste the MCP server URL https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID.
3. Muse opens the AnythingMCP sign-in page: sign in and approve access.
4. In a chat, ask Muse for something that needs the Perplexity API tools.

You can also set it up from a chat, on the web, in the iOS and Android apps or in WhatsApp. Send Muse this message:

Create a Custom Connector for a new remote MCP server, then connect to it:
Name: AnythingMCP
Transport: remote streamable HTTP
URL: https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID
Auth: OAuth

Self-hosting? Use your instance's public HTTPS address instead of https://cloud.anythingmcp.com. Muse connects from Meta's cloud, so localhost does not work.

Available tools

Example prompts

• "What changed in the EU battery regulation this year? Answer with sources."
• "Find recent articles on remote work productivity and give me just the links and snippets."
• "Only using sources from europa.eu, what are the current roaming rules for business travellers?"
• "Start a deep research run on the European market for refurbished laptops, but check the preset with me first."

FAQ

Where is Muse available? Meta currently offers Muse in the US and Canada, on the web, in the iOS and Android apps and in WhatsApp.

Does Meta review this connector? No. Meta doesn't review custom connectors. Muse sees only the tools you switched on for this MCP server in AnythingMCP, and you can disconnect it anytime under Settings → Connectors.
